Tactical building door opener

Abstract

A portable, tactical building door opener comprises a door opening mechanism comprising: a body; a door opening arm pivotally connected to the body at a first end and having a roller for engaging the surface of the door at a second end; and an actuator for rotating the door opening arm with respect to the body, from a ready position in which the roller is not forced against the surface of the door, to a door-opened position in which the roller is forced against the surface of the door to open the door. The actuator is remotely and manually operable. The device further includes a support for temporarily and removably bracing the door opening mechanism with respect to the door.

1. A portable, tactical building door opener for opening a door, comprising:
 a door opening mechanism comprising: 
 a body; 
 a door opening arm pivotally connected to said body at a first end of said arm and having a roller for engaging a surface of said door at a second end of said arm; and 
 an actuator for rotating said door opening arm with respect to said body, from a ready position in which said roller is not forced against the surface of said door, to a door-opened position in which said roller is forced against the surface of said door and has moved said door to an open position; 
 said actuator being remotely and manually operable; and 
 support means for temporarily and removably bracing said door opening mechanism with respect to a frame of said door, wherein said support means comprises a spreader bar positioned within said frame of said door and engaging a hinge jamb of said frame at one end of said bar and engaging a latch jamb of said frame at another end of said bar. 
 
   
   
     2. The door opener of  claim 1 , wherein said spreader bar interference fits within said frame of said door. 
   
   
     3. The door opener of  claim 2 , wherein said spreader bar comprises two mating tubes, said tubes having alignable mating holes and a spring-loaded button alignable with said holes. 
   
   
     4. The door opener of  claim 2 , wherein said spreader bar comprises a sharp point at said ends thereof for engaging with said door frame. 
   
   
     5. The door opener of  claim 2 , further comprising rubber feet which may be removably mounted on the ends of said spreader bar, for engaging with said door frame. 
   
   
     6. The door opener of  claim 2 , further comprising two adjustable clamps mounted on said body, for gripping said spreader bar. 
   
   
     7. The door opener of  claim 2 , wherein said actuator comprises a pneumatic cylinder. 
   
   
     8. The door opener of  claim 7 , wherein said pneumatic cylinder is pressurized by rotating said door opening arm from said door opened position to said ready position. 
   
   
     9. The door opener of  claim 8 , further comprising a latch mechanism to hold said pneumatic cylinder when pressurized. 
   
   
     10. The door opener of  claim 9 , wherein said latch mechanism is operated to release said pneumatic cylinder by pulling on a line. 
   
   
     11. The door opener of  claim 2 , wherein said actuator comprises a spring. 
   
   
     12. A portable, tactical building door opening system for opening a door, comprising:
 means for unlatching said door; 
 a door opening mechanism comprising: 
 a body; 
 a door opening arm pivotally connected to said body at a first end of said arm and having a roller for engaging a surface of said door at a second end of said arm; and 
 an actuator for rotating said door opening arm with respect to said body, from a ready position in which said roller is not forced against the surface of said door, to a door-opened position in which said roller is forced against the surface of said door and has moved said door to an open position; 
 said actuator being remotely and manually operable; 
 support means for temporarily and removably bracing said door opening mechanism with respect to a frame of said door; wherein said support means comprises a spreader bar positioned within said frame of said door and engaging a hinge jamb of said frame at one end of said bar and engaging a latch jamb of said frame at another end of said bar; and 
 means for operating said means for unlatching said door and said actuator manually and remotely. 
 
   
   
     13. The building door opening system of  claim 12 , wherein said means for unlatching said door comprises a lever which is removably fastened to a knob on said door. 
   
   
     14. The building door opening system of  claim 13 , wherein said means for operating comprises a single line which is routed to operate said means for unlatching and said actuator when pulled.
